Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free compliance and specific manufacturing lot details. Confirm the SOIC-24 package variant matches the design footprint requirements. Ensure the operating temperature range aligns with the target application environment specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered transceiver with TTL compatibility is required. The 5.5 ns propagation delay suits moderate-speed digital applications. Verify that the 12 mA/15 mA drive current meets load requirements. Consider the SOIC-24 package dimensions for PCB layout constraints compared to alternative packages like TSSOP or QSOP.
